SEPARATOR FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent N 0. 542,649, dated July16, 1895. Application filedMerch 19,1395. S ia1No.54 2,362. (No11101181.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR MASON, a citizen of the United States,residing at Taunton, in the county of Bristol and Commonwealth ofMassachusetts, have invented anew and useful Improvement in Separatorsfor Spinning-Frames, of which the following is a specification,reference being had to the accompanying drawings, which form a parthereof.

The object of my invention is to construct a separator in which a wideblade may be used for long winds as conveniently as a narrow blade, andwhich shall at all times be within a perpendicular line from the face ofthe ring-rail also, to cause the separatorblade to be automaticallythrown down again when the machine starts after the blades have beenlifted for doffing or other purpose, and to provide a counterbalance forthe separator-- blades, which shall serve also as a stiffeningro Myinvention consists in a pivoted trippinglever connected with thewave-rocker and actuated by the wave-rocker to trip the separator andthrow it from an upright position into its operative position before thelevers carrying the separator-blades are turned on their pivots; also,in, certain adjustable features of the levers and in making acounterbalance,

which serves also as a stiffening-rod and bears against the salnson as astop, and in other features which will be more particularly describedand claimed.

In the drawings, Figure 1 is a cross-section through the roll-beam,showing an end elevation of so much of a spinning-frame as is necessaryto illustrate my invention. Fig. 2 is a section through the dog on thewave-rocker rail S, ring-rail S, andlower rail S are common, and poweris applied inthe usual manner. The samson M supports the roll-beam andother parts of the spinning-frame.

Secured to theroll-beam A is a bracket D, having an elongated slot d,.in which is clamped a stud J, which forms a pivot for the bent lever O,at the forward end of which is pivoted the separator O. The bent lever Eis also pivoted on the same stud J, and has-an extension E, with a slot6, through which a bolt 6' passes, bolting the two levers E and 0together, so that they move on the pivot as one lever. The toothedindicator L engages with the toothed segment K, and is set in the propernotch before the bolt 6 is set up. By observing the position of thepointer on the segment all the separator-levers in the line can be setat exactly the same position.

The stiffening-rod H runs the length of the machine, resting on all thelevers E in the line, and is clamped to each one by a dog G. This servesto hold them all at a uniform position and serves also as acounterweight. It is so adjusted that the blades will over- -weigh therod H sufficiently to assure that the separator-blades will fall bytheir own weight when the wave-rocker shaft W turns in its bearings Rand relaxes the strain on the rod Q, the samson on M serving as a stop.

The wave-rocker W is actuated through the rocker-armX andreciprocating-shaft Y.

The tripping-lever B, which throws down the separator in the mannerwhich will be described later on, is pivoted to the lever O at b, and atits rear end is a stud b, which plays up and down in a vertical slot 12in the arm 0 of lever O, the tripping movement being given by the wirerod Q, actuated by the rocker-shaft W.

The separator O is clamped to the holder I by screw-bolt O, which passesthrough an elongated slot 0 in the bent shank O of the separator. Thisholder consists of a sheet of metal having a series of elongated slotst', through which the screw-bolts 0 pass, the separator thereby beingcapable of delicate adjustment to the proper alignment for its throwbetween the bobbins.

The pivot P by which the separator is pivoted to the lever O is securedin the bracket P, which is also clamped to the holder-plate I by thescrew-bolt O. I prefer to make this holder-plate I of corrugated sheetmetal, because it is light and is sufficiently strong for the purposeand is of a form which will be readily engaged by the tripping-lever B.This tripping-leverB has-an upturned end B, which, when the lever B ispulled down by the rod Q,bears up against the holder I on one side ofits center and throws it over on its pivot.

The wire rod Q is adjustable in length by means of the turn-buckle QT,and at its lower end it is fastened to a chain V, which is socured tothe dog F on the rocker-shaft W.

During the operation of winding the separator is between the bobbins, asshown in fulllines in Fig. l. The holder-plate I strikes on a shoulder Con the lever C to prevent turning too far down on its pivot and the rodQ should preferably be adjusted in length so that the separator shall atall times be. held out of contact with the. ringrail. As the.rocker-shaft R rocks, giving the up-and-down movement to the ring-rail,the. chain V will wind and unwind over the deg F and give a.reciprocating movement to the rod Q, thereby turning the levers E and B.on their pivot and causing the separator O to alsorise and fall at acorresponding rate of speed as the. ring-rail. hen dotting the separatoris thrown back on its pivot and maycome u p. against the roll-v beam.Heretofore when a wide separator is used, which is attached to theroll-beam as it projects out over the path of thering-rail, if'theoperator forgets to throw the separator dew-n again after dofflng andbefore starting up the machine the rail will strike the separator andbreakage of something will take place. In my device the separator neednot be thrown back by hand. As soon as the machine starts the.rocker-shaft R turns, Winding the chain and pulling down the rod Q assoon as. itsis in its lowest position as regulated bythe rod 1-1 when itbears up against the. Samson, and the slack should not be so great butthat it will be all taken up, at the. proper time for trippingtheseparator when the ring-rail rises again.

What I claim is 1 In a spinning frame, the combination of a separator, aseparator lever towhich; the separator is pivoted,,a supportin which theseparator lever is fulcrumed, mechanism and. causes the separator to.rise in ad vanoe of the ring rail when the separator is in its op.-erative position between twov bobbins, and a tripping device which,throws the separator down into its operative position between thebobbinsv before the separator lever turns on its fulcrum to lift theseparator, substantially as described.

2. The combination of a separator, a sepa rator lever, a fulcrum forsaid lever intermediately between its ends, a tripping lever and afulcrum for the tripping lever intermediately between its ends, a rodpivoted at its upper end to the rear arm of the tripping lever and tothe rear arm of the separator lever, the pivot for said rod having playin a slot in the separator lever, a wave rocker, said rod having at itslower end a flexible connection with the wave rocker whereby, when therocker turns, the tripping lever will be turned onfiits fulcrum to throwthe raised separator blade into operative position, before the separaterleverbegins to move onits fulcrum, suba; fulcrum for the tripping leverintermediately between its. ends, a rod pivoted at its upper end to therear arm of the separator lever, the pivot for said rod having play in aslot, in the separator lover, a wave rocker, said rod, having at. itslower end a flexible connection with the wave rocker, and a cam dog on,the rocker which guides the flexible portion whereby, when said rockerturns, thetripping lever will be turned on its fulcrum to throw theraised separator blade into operative position, substantially asdescribed.

4. In a spinning frame, the combination of a. Series of separatorlevers, a series of brackets in which the separator levers arefulcrumed, a. series of separators pivoted to the forward arms of saidlevers, and a stiffening rod which serves as a. common counterweight forsaid separators adjustably secured to the rear arms of said levers,substantially as de scribed.

5 A separator lever composed of two bars having overlapping ends. boltedtogether, a

toothed segment on one bar and av toothed guide on the other engaging insaid toothed segmentwhereby the, two bars. maybe set at Various anglesto eachv other, substantially as described.

6. In a. spinning frame, the combination of a series of bracketssupported from the roll beam, a series, of separatorlevers pivoted insaid brackets, a stiffening rod extending transversely of all theseparator levers in said seriesand serving as a common counterweight,and a. series of dogs which clamp said rod to the levers, substantiallyas described.

7. In aspinning frame, a series, of separators each, having a bladeO anda bentshank 0- formed. with flanged sides an dan elongated which turnsthe separator lever on itsfulcrum slot. 01 in combination. with avcorrugated jmetal holder I embraced by the separator shanks, and having,aseries of elongated slots which register with the slots in theseparator shank, and bolts which pass through said slots holders, abracket P also bolted to the sepa rator holder, and a separator lever towhich the bracket is pivoted substantially as described.

9. The combination of the bent levers C and E bolted together andforming a lever for the separator blade, a movable pivot on which saidlevers are fulcrumed, and a tripping lever pivoted to the separatorlever, substantially as described.

10. The combination of the bent levers O and E bolted together andforming a lever for the separator blade, an adjustable pivot on whichsaid levers are fulcrumed, a toothed segment and indicator whereby thetwo levers C and E maybe adjusted to different angles with relation toeach other, a tripping lever pivoted to the compound separator lever, arod H which is adjustably secured to the rear arms of a series ofseparator levers and which serves as stiffening rod and counterbalance,and which bears against the samson which forms a stop, substantially asdescribed.
